Just No Brake Lights

[Aubrey3]

I have no brake lights and need some help. I have tail lights, hazards, left and right turn, but I don't have brake lights.

The previous owner said there were no brake lights and he had replaced the brake switch under the hood. There is a red wire on it closest to the firewall which goes into the cab. It has power when Accessory on. From that wire that goes in there is another red that routes down to the frame rail. It has a quick connector. I disconnected it and I get know power from the end that comes from in the cab.

On the other side of the switch is a green wire that goes down to the frame rail. When on Accessory and a jumper between those two poles on the switch the solenoid triggers, but no lights.

What does the green wire go to?
What does the dead red wire come from?
Any ideas on where the problem is?

Thank you for your help.

Check under your dash at the Brake pedal. There should be a switch for the Brake Lights there, (not sure about '66). Make sure that the switch is there and that it is being pushed when the pedal is moved (when you apply the brakes) and , of course, make sure the connector is attached. Maybe look for broken/ loose wires, etc. at or near this switch. I hope this helps.

Actually I have a hydraulic pressure brake switch. I think it is a wire connection towards the flasher. Need to locate that maybe tomorrow.

I have brakes!
See attached photo and commentary.

The red that routed to the frame rail, I disconnected and from the loom I put it to the switch. It works, but now I have a red coming up from the frame rail. What does this go to?
The green that was on the switch, I disconnected from the switch, but now I have a green coming up from the frame rail. What does this go to?
